DETAILED DESCRIPTION

With reference now to the drawings, and in particular to FIGS. 1 through 9 thereof, a new aggregate transferring system embodying the principles and concepts of the disclosed subject matter will be described.

The applicants have recognized that an apparatus for transferring aggregate, such as from a vehicle to a storage silo, would be particularly advantageous if the apparatus had the capability to deploy itself at the location of transfer without the need for any significant assistance from other apparatus, such as cranes or telescopic handlers (e.g., “tele-handlers”). The ability of the apparatus to “self deploy” can minimize the complexity of the deployment operation by eliminating any need to provide the additional apparatus at a work site, likely reducing the number of personnel involved in the deployment operation, as well as eliminating the need to coordinate the movements of the additional apparatus with respect to the aggregate transferring apparatus (as well as the dangers inherent with such coordination). Moreover, the applicants have also recognized the advantages provided by an aggregate transfer apparatus which is highly integrated such that all of the major components of the apparatus are able to be transported as a unit between locations without elements being hauled by separate transport.

In one aspect, the disclosure relates to an aggregate transferring apparatus 10 for transferring aggregate, as will be illustratively described. The apparatus 10 is suitable for performing the transfer of aggregate from one location to another, such as, for example, from a vehicle carrying the aggregate to a silo 1 for storing the aggregate. Illustratively, the aggregate transferring apparatus 10 may be utilized for transferring an aggregate such as sand, and in some implementations the sand may be of the type utilized in the process of hydraulic fracturing in connection with subterranean petroleum drilling. The vehicle may comprise a truck suitable for carrying the aggregate, and dumping or otherwise dispensing the aggregate, such as a bottom dump trailer. The silo may be positioned on the ground surface and may be vertically elongated with a top elevated above the ground surface, and the top have a port 2 which may be open, or openable (and closable), to receive the aggregate into the interior of the silo. In some applications, more than one silo may be grouped together adjacent to each other, such as in a two silo wide by three silo length array.

The aggregate transferring apparatus 10 may have an operational configuration (see, e.g., FIGS. 1A, 1B, 4 . 5D, 7A, 7D, and 8A through 8F) in which the apparatus is configured to receive the aggregate, and then transport or convey the aggregate to a position elevated above the ground surface so that the aggregate may be dispensed into a silo, such as through the open top of the silo. The aggregate transferring apparatus 10 may also have a transport or travel configuration (see, e.g., FIGS. 2A, 2B and 3 ) in which the apparatus is suitable to be moved from one location to another, such as by towing the apparatus over roads and highways. In general, in the operational configuration, the apparatus may be relatively extended and expanded, while in the transport configuration the apparatus may be relatively collapsed and compact to facilitate movements on roads.

In greater detail, the aggregate transferring apparatus 10 may include a base assembly 12 for receiving aggregate to be conveyed by the transferring apparatus and forming the portion of the apparatus 10 generally extending along and engaging the ground surface, particularly in the operational configuration. The base assembly 12 may comprise a base frame 14 which may be elongated along a longitudinal axis 16 of the frame 14 and the assembly 12. The base frame 14 has a leading end 18 and a trailing end 19, with the leading end being generally oriented toward the normal direction of movement of the apparatus 10 when the apparatus is being moved in the transport configuration. The frame 14 may have a leading portion 20 which includes the leading end 18 as well as the portion of the base frame adjacent to the leading end, a trailing portion 22 which includes the trailing end 19 as well as the portion of the base frame adjacent to the trailing end. The base frame 14 may also include a medial portion 24 which is positioned between the leading 20 and trailing 22 portions.

The base assembly 12 may also include at least one axle 26 which is mounted on the base frame 14, and a pair of wheels 28 which are mounted on opposite ends of the axle 26. Typically, to enhance the move ability of the apparatus 10 over highways, the base assembly will include a plurality of axles positioned along the base frame in the longitudinal direction of the base frame. Illustratively, the plurality of axles 26 and corresponding wheels 28 are located on the medial portion 24 of the base frame. In some embodiments, the axles are mounted on the base frame 14 utilizing one or more tandem walking beams, although other suspension structures may be utilized.

In some embodiments, the base assembly 12 may include an outrigger structure 30 mounted on the base frame 14 for enhancing the stability of the operational configuration of the apparatus 10, as well as the stability as the apparatus moves between the operational and transport configurations. The outrigger structure 30 may be positioned on the base frame 14 toward the trailing end 19, such as on the trailing portion 22 of the frame 14. The outrigger structure may be movable with respect to the base frame 14, and may be movable between a stabilizing condition (see, e.g., FIGS. 1A, 1B and 4 ) and a non-stabilizing condition (see, e.g., FIGS. 2A, 2B and 3 ). In general, the non-stabilizing condition of the outrigger structure 30 may correspond to the transport configuration of the apparatus 10 while the stabilizing condition of the structure 30 may correspond to the operational configuration of the apparatus. The stabilizing condition of the outrigger structure 30 may also be utilized when the apparatus 10 is moving from the transport condition to the operational condition, and also when the apparatus is moving from the operational condition to the transport condition.

In some greater detail, the outrigger structure 30 may include at least one outrigger arm 32 which is mounted on the base frame 14, and the outrigger arm may be pivotable with respect to the base frame. The outrigger arm 32 may be oriented substantially perpendicular to the longitudinal axis 16 of the base frame in the stabilizing condition of the outrigger structure, and may be oriented substantially parallel to the longitudinal axis in the non-stabilizing condition of the outrigger structure. In some of the most preferable embodiments, a pair of the outrigger arms 32, 34 is utilized and each arm is pivotally mounted on the base frame. The pair of outrigger arms 32, 34 may extend in substantially opposite directions from each other in the stabilizing condition and the arms may extend substantially parallel to each other in the non-stabilizing condition. Further, the pair of outrigger arms 32, 34 may be positioned astride of the wheels 28 on the axles when the outrigger structure is in the non-stabilizing condition.

The outrigger structure 30 may further include at least one outrigger leg 33 that is configured to extend downwardly from one of the outrigger arms 32, 34 to contact the ground surface below the outrigger arm. The outrigger leg 33 may have an extended position in which the leg 33 is extended away from the outrigger arm toward the ground surface to contact the ground surface for providing stability to the apparatus 10. The outrigger leg 33 may also have a retracted position in which the leg 33 is retracted toward the outrigger arm and away from the ground surface. A pair of the outrigger legs 33 may be provided, with each outrigger leg being mounted on one of the outrigger arms 32, 34. The extended position of the outrigger legs 33 may correspond to the deployed mode of the apparatus 10 and the retracted position of the outrigger leg may correspond to the storage mode of the apparatus. An outrigger leg actuator 35 may be provided for each outrigger leg 33 to move the outrigger leg between the extended position and the retracted position, and the actuator 35 may be connected to the outrigger arm and the outrigger leg to act between the arm and leg.

Additionally, at least one stabilizing leg 36 may be provided that is extendable downwardly from the base frame 14 to contact the ground surface below the apparatus 10. The stabilizing leg 36 may have an extended position in which the leg 36 is extended away from the base frame 14 toward the ground surface to contact with the ground surface and a retracted position in which the leg 36 is retracted toward the base frame and away from the ground surface. A plurality of the stabilizing legs 36 may be utilized, and may include a pair of the stabilizing legs each being mounted on the base frame 14. The pair of stabilizing legs 36 may be located toward the trailing end 19 of the base frame, and may be laterally offset from a central longitudinal axis of the base frame, such as or locations between the outrigger legs 33 mounted on the outrigger arms 32, 34 (see, e.g., FIG. 4 ). The extended position of the stabilizing legs 36 may correspond to the deployed mode of the apparatus and the retracted position of the stabilizing legs may correspond to the storage mode of the apparatus, A stabilizing leg actuator 37 being configured to move the at least one stabilizing leg between the extended position in the retracted position, the stabilizing leg actuator acting between the base frame and the stabilizing leg,

The base assembly 12 may further comprise an unloader structure 40 for receiving the aggregate from the vehicle carrying the aggregate to the apparatus 10. The unloader structure 40 may be mounted on the base frame 14, and may be positioned toward the leading end 18 of the frame 14 and on the leading portion 20 of the frame (but also may be spaced from the leading end of the frame). The unloader structure 40 may have a transport condition and an operational condition, with the transport condition generally corresponding to the transport configuration of the apparatus 10 and the operational condition generally corresponding to the operational configuration of the apparatus. The unloader structure may include a pair of ramps 42, 44 mounted on the base frame 14, with each of the ramps being pivotable with respect to the base frame. In the operational condition, the ramps 42, 44 may extend laterally from the base frame 14 in substantially opposite directions in the operational condition, and may be oriented substantially horizontally for contacting the ground surface. In the transport condition, the ramps may be oriented substantially parallel with respect to each other, and may extend substantially vertically upwardly from the base frame 14. Illustratively, each of the ramps 42, 44 may comprise a pair of ramp portions 46, 47 positioned adjacent to each other, although a ramp comprised of a single ramp portion may also be utilized. Each of the ramps 42, 44, and ramp portions 46, 47 if utilized, may have a position corresponding to the transport condition of the unloader structure 40 and also have a position corresponding to the operational condition of the unloader structure. At least one ramp actuator 45 may be provided which is configured to move at least one of the ramps between the position corresponding to the transport condition and the position corresponding to the operational condition. Typically, a plurality of the ramp actuators 45 may act on the ramps 42, 44 (and ramp portions 46, 47 if utilized) to move the ramps, and/or the portions of the ramps, between the positions corresponding to the transport and operational conditions of the unloader structure.

The unloader structure 40 may further include a grate 48 mounted on the base frame 14 that may be substantially horizontally oriented and positioned between the pair of ramps 42, 44, and at least a portion of the grate may be reticulated with holes to permit aggregate landing on the grate to pass through the grate.

Further included in the base assembly 12 may be a base conveyor 50 mounted on the base frame 14 and which extends along a longitudinal portion of the base frame between the leading 18 and trailing ends of the base frame. The base conveyor 50 may tend to move aggregate falling onto the conveyor toward the trailing end 19 of the frame 14. The base conveyor 50 may have a receiving end 52 and a dispensing end 54, with the receiving end being located toward the leading end 18 and the dispensing end being located toward the trailing end 19 of the base frame. The base conveyor 50 may comprise a base conveyor belt 56 for carrying aggregate away from the unloader structure 40, and at least a portion of the belt 56 may be positioned below the grate 48 such that gravity moves the aggregate through the grate and onto an upper stretch or portion of the belt supporting aggregate being carried by the belt. The base conveyor 50 may have a plurality of support rollers 58 which are mounted on the base frame 14 and extend laterally with respect to the longitudinal axis 16 of the base frame to support the upper stretch of the base conveyor belt.

The aggregate transferring apparatus 10 may further include an aggregate elevating assembly 60 for elevating aggregate received from the base assembly to a relatively higher vertical level or elevation above the ground surface. The aggregate elevating assembly 60 may include a deployable frame 62 which is movably mounted on the base assembly 12. The deployable frame 62 may be mounted on the base frame 14, and may be located toward the trailing end 19. The deployable frame 62 may be elongated with a base end 64 and a free end 66, with the base end being mounted on the base assembly 12. The deployable frame 62 may be movable between a storage position generally corresponding to the transport configuration of the apparatus 10, and a deploy position generally corresponding to the operational configuration of the apparatus. The storage position of the deployable frame 62 may be characterized by the frame 62 being substantially horizontally oriented and generally parallel to the base frame 14 and the ground surface. The deploy position of the deployable frame 14 may be characterized by the frame 14 being oriented substantially vertical, and oriented substantially perpendicular to the base frame 16 and the ground surface. In illustrative embodiments, the deployable frame 62 comprises a truss frame with a space frame about a substantially hollow interior.

The aggregate elevating assembly 60 may also include trailer structure 70 which is configured to provide trailer functionality to the elevating assembly, and by extension the aggregate transferring apparatus 10, when the apparatus 10 is in the transport configuration such that the apparatus 10 may be towed across the ground surface. The trailer structure 70 may be positioned adjacent to, and typically in contact with, the ground surface when the deployable frame is in the storage position (and other elements of the apparatus 10 are in the transport configuration). In greater detail, the trailer structure 70 may include at least one landing leg 72 mounted on the deployable frame 62 to rest upon the ground surface when the deployable frame is in the storage position, and the leg may extend outwardly from the frame 62. Typically, a pair of the landing legs 72, 74 may be utilized with each of the legs having similar orientation with respect to the frame 62. The trailer structure 70 may further include a kingpin 76 mounted on the deployable frame 62 which is able to engage the fifth wheel hitch structure of a vehicle, such as a semi-tractor, for towing the apparatus 10 in the transport configuration. The kingpin 76 may be located toward the free end 66 of the deployable frame 62, and may be directed in the same direction as the landing leg or legs such that the kingpin and the landing legs are directed downwardly toward the ground surface when the apparatus 10 is in the transport configuration. In some embodiments, the free end 66 of the deployable frame 62 may extend beyond the leading end 18 of the base frame 14 when the deployable frame is in the storage position so that the trailer structure is able to move past the base assembly 12 and engage the ground surface.

The aggregate elevating assembly 60 may further include an elevating conveyor 80 for conveying aggregate upwardly from the base assembly 12. The elevating conveyor 80 may extend longitudinally with respect to the deployable frame 62, and may extend from the base end 64 to the free end 66 of the frame 62. The elevating conveyor 60 may be configured to receive aggregate from the base conveyor, and may have an intake 82 and an output 84. The intake 82 may be being located toward the base end 64 of the deployable frame 62 and also may be located adjacent to the dispensing and 54 of the base conveyor 50 to receive aggregate from the conveyor 50. The output 84 may be located toward the free end 66 of the deployable frame, and may be configured to output the conveyed aggregate on the side of the frame 62 that is opposite of the side of the frame 62 at which the intake is located. In some embodiments, the elevating conveyor 80 may comprise a bucket conveyor, and the conveyor 80 may be at least partially within the truss frame of the deployable frame 62. Illustratively, the elevating conveyor 8 may have a length of support to 70 feet or more.

The aggregate transferring apparatus 10 may also include a frame deployment assembly 90 which is configured to move the deployable frame 62 of the elevating assembly 60 with respect to the base frame 14 of the base assembly 12. The frame deployment assembly 90 may be configured to move the deployable frame between the storage and deploy positions for converting the apparatus 10 between the transport and operational configurations. The frame deployment assembly 90 may be mounted on the base frame 14 and the deployable frame 62.

In illustrative embodiments, the frame deployment structure 90 may comprise at least one lift arm structure 92 mounted on the base frame 16 and the deployable frame 62 which may form a linkage between the base frame and the deployable frame.

Illustratively, the frame deployment assembly 90 may include a pair of the lift arm structures 92, 94 mounted on the base 14 and deployable 62 frames. In general, the pair of lift arm structures 92, 94 may be laterally spaced with respect to the longitudinal axis 16 of the base frame, and may be located on opposite lateral sides of the deployable frame 62. Each of the lift arm structures 92, 94 may have a first end 96 which is mounted on a base mount point 98 on the base frame 14 which may permit pivotal movement of the first end 96 with respect to the base mount point 98. Further, each of the lift arm structures 92, 94 may have a second end 100 mounted on an upper mount point 102 on the deployable frame 62. The upper mount point 102 may include a cross-member 104 that extends between the pair of lift arm structures 92, 94 and that is mounted on the deployable frame.

In some embodiments, each of the lift arm structures 92, 94 may be articulated between the first 96 and second 100 ends such that the structures 92, 94 articulate as the deployable frame 62 moves between the storage and deploy positions and the apparatus moves between the transport and operational configurations. Each of the lift arm structures 92, 94 may include a first link member 106 and a second link member 108 which are pivotally mounted together. The first link member 106 may have the first end 96 of the respective lift arm structure, and the first link member may be pivotally mounted on the base mount point 98 to pivot with respect to the base frame 14. The first link member 106 may be elongated in shape and have a first intermediate end 110 located on the member 106 opposite of the first end 96 of the lift arm structure. Illustratively, the first link member 106 may be formed by a bar. The second link member 108 may have the second end 100 of the respective lift arm structure, and the second link member may be pivotally mounted on the upper mount point 102 to pivot with respect to the deployable frame 62. The second link member 108 may be elongated in shape and have a second intermediate end 112 located on the member 108 opposite of the second end 100 of the lift arm structure. The second intermediate end 112 of the second link member may be pivotally mounted to the first intermediate end 110 of the first link member. The second link member may form a medial mount point 114. Illustratively, the second link member 108 may comprise a bar and a weldment.

The frame deployment structure 90 may further include lift actuator 116 which acts on at least one of the lift arm structures 92, 94. The lift actuator 116 may be mounted on the base frame 14 and the respective lift arm structure, and may be mounted on the base mount point 98 on the base frame and the medial mount point 114 on the second link member 108 of the respective lift arm structure. The lift actuator 116 may be extendable and retractable in length to move the second link member 108 with respect to the base frame. Illustratively, the lift actuator may comprise a hydraulic actuator, although other types of actuators may also be employed.

The aggregate transferring apparatus 10 may further include a conveyor extension assembly 120 for conveying aggregate to locations horizontally outward from the aggregate elevating assembly 60, such as, for example, one or more silos to which the apparatus 10 is positioned adjacent. The conveyor extension assembly 120 may include an extension conveyor 122 for moving aggregate from the aggregate elevating assembly 60 to a location outward from the assembly 60. The extension conveyor 122 may be movable with respect to the elevating assembly 60, and may be extendable outwardly from the assembly 60 in a substantially horizontal orientation. The extension conveyor 122 may be movable between a lowered position (see. e.g., FIG. 2A) and a raised position (see. e.g., FIG. 5D). FIGS. 5A through 5C illustrate three illustrative intermediate positions of the extension conveyor 122 between the lowered position of FIG. 2A and the raised position of FIG. 5D. The lowered position of the extension conveyor 122 may correspond to the transport configuration of the apparatus 10, and the raised position of the conveyor 122 may correspond to an operational configuration of the apparatus. The lowered position may be further characterized by the extension conveyor 122 being positioned adjacent to the deployable frame 62 of the aggregate elevating assembly 60, and the extension conveyor may be oriented substantially parallel to the deployable frame 62 in the lowered position. The raised position of the conveyor 122 may also be characterized by the extension conveyor being positioned generally away from the deployable frame 62, and the extension conveyor may be cantilevered outwardly from the deployable frame in the raised position. The raised position of the extension conveyor 122 may further be characterized by the conveyor 122 being oriented substantially perpendicular to the deployable frame 62 of the aggregate elevating assembly. As illustrated in FIGS. 5A through 5D, the extension conveyor 122 may be maintained in a substantially horizontal orientation (e.g., substantially parallel to the base frame 14) as the deployable frame 62 of the elevating assembly 60 is raised from the storage position to the deploy position, and similarly the conveyor 122 may be maintained and the substantially horizontal orientation as the frame 62 is lowered from the deploy position to the storage position.

The extension conveyor 122 may have an inlet 124 for receiving aggregate from the aggregate elevating assembly 60 and an outlet 126 for dispensing aggregate from the extension conveyor to a desired location, such as into the port 2 at the top of a silo.

The conveyor extension assembly 120 may comprise an inboard segment 130 and an outboard segment 132, with the inboard and outboard segments being articulated with respect to each other to permit adjustment of the position of the outlet 126 with respect to the inlet 124 including the effective distance between the outlet 126 and the inlet 124. The inboard segment 130 may be pivotally connected to the deployable frame 62 of the aggregate elevating assembly by an inboard pivot 134, which may permit pivoting of the inboard segment 130 with respect to the deployable frame about a substantially vertical axis. The outboard segment 132 may be pivotally connected to the inboard segment 130 by an outboard pivot 136, which may permit pivoting of the outboard segment 132 with respect to the inboard segment 130 about a substantially vertical axis. The inboard segment 130 has a first inboard segment end 138 mounted on the deployable frame 62, and may be configured to receive aggregate from the output 84 of the elevating conveyor 80. The inboard segment 130 may also have a second inboard segment end 140 which is located opposite of the first inboard segment end 138 on the segment 130, and may also be located at the outboard pivot 136. The outboard segment 132 has a first outboard segment end 142 which is located at the outboard pivot 136 and which may be pivotally mounted on the second inboard segment end 140 of the inboard segment 130. The outboard segment 132 has a second outboard segment end 144 which is located opposite of the first outboard segment end 142, and the outlet 126 of the extension conveyor may be located at the second outboard segment end. Movement of the inboard segment with respect to the deployable frame at the inboard pivot, and the outboard segment with respect to the inboard segment at the outboard pivot, may be accomplished using any suitable mechanism. In some embodiments, an inboard pivot actuator 135 may be configured to pivot the inboard segment 130 with respect to the deployable frame 62, and the inboard pivot actuator may act between the deployable frame and the truss frame of the inboard segment. Additionally, an outboard pivot actuator 137 may be configured to pivot the outboard segment 132 with respect to the inboard segment 130, and the outboard pivot actuator may act between the inboard and outboard segments. Illustratively, the inboard pivot actuator 135 and the outboard pivot actuator 137 may comprise, such as, for example, a slew drive mechanism which may be highly suitable for permitting transfer of aggregate from the elevating conveyor 80 to inboard segment 130 of the extension conveyor 122, and from the inboard segment to the outboard segment 132 of the extension conveyor.

Each of the inboard 130 and outboard 132 segments may have substantially similar constructions. Illustratively, each segment may include a truss frame 146 and a plurality of support rollers 148 rotatably mounted on the truss frame 146. Each segment may further include a conveyor belt 150 which may be an endless belt supported on the support rollers 148, and an upper wall 152 may be mounted on the truss frame in a position above the conveyor belt to at least partially cover an upper stretch of the conveyor belt as well is aggregate carried by the upper stretch.

In some embodiments, when in the transport configuration of the apparatus 10, the inboard segment 130 of the extension conveyor 122 may be positioned over a portion of the deployable frame 62 of the aggregate elevating assembly, and the outboard segment 132 of the extension conveyor may be positioned laterally alongside a portion of the deployable frame 62.

The conveyor extension assembly 120 may also comprise a conveyor support frame 154 for supporting the segments 130, 132 of the extension conveyor on the aggregate elevating assembly 60. The conveyor support frame 154 may be movable with respect to the deployable frame 62 of the elevating assembly when the extension conveyor 122 moves between the lowered and raised positions, and the conveyor support frame may be pivotally mounted on the deployable frame to permit pivoting of the support frame 154 with respect to the deployable frame about a substantially horizontal axis.

Illustratively, image sensors 176 may be positioned adjacent to the chute 164, and may be directed downwardly from the second outboard segment end 140 for capturing images of the position of the spout 166 below with relation to, for example, the port 2 of a silo 1. Additionally, image sensors 176 may be positioned at other locations on the apparatus 10 where visual information would be helpful, such as, for example, the upper free end 66 of the deployable frame 62 looking downwardly on the apparatus 10 using one or more of the image sensors. Images produced by the image sensors may be displayed on a display screen or monitor. The control assembly 170 may further include sensors for sensing positions of various elements, such as a plurality of segment position sensors 182 for sensing positions of the inboard 130 and outboard 132 segments of the extension conveyor. Illustratively, each of the segment position sensors 178 may be located at one or all of the inboard 134 and outboard 136 pivots, and each position sensor may be associated with one of the pivot actuators 135, 137 to sense and communicate the relative positions of the elements connected at the respective pivot. For example, an encoder device may be associated with each slew drive mechanism of the pivot actuators.

Broadly, the control assembly 170 may also include elements of the apparatus 10 which receive commands or signals from the controller 172 (or operator-manipulated manual controls) in order to operate elements of the apparatus 10, such as the power control circuitry which provides electrical power to elements of the apparatus such as the motors and valves which control the supply of hydraulic fluid to elements of the apparatus such as hydraulic actuators.

The control assembly 170 may implement automatic or semi-automatic functionality in the operation of the various powered elements of the apparatus 10 to provide safety and convenience in the operation of the apparatus. As an example, for elements for which the initiation or termination of operation of the elements in a sequential manner is desirable or necessary, the controller 172 may be programmed to initiate or terminate the operation in the sequence in response to a single input or command from the operator. Further, memory 184 associated with the controller 172 may retain information for enabling repeated movements by or positioning of elements of the apparatus. For example, the relative positions of the inboard 134 and outboard 136 segments of the extension conveyor 122 corresponding to the loading of specific silos in the silo array may be stored in memory 184 such that the controller 172 is able to recall the position and orientation information of the elements from the memory when invoked or requested by the operator in order for the controller to operate elements of the apparatus 10 to cause the chute 164 to be moved to a location suitable to dispense aggregate to the identified silo of the array from the spout 166.
